Cumulative density distribution

WebNormalDistribution [μ, σ] represents the so-called "normal" statistical distribution that is defined over the real numbers. The distribution is parametrized by a real number μ and a positive real number σ, where μ is the mean of the distribution, σ is known as the standard deviation, and σ 2 is known as the variance.

density function - What should the integral of a CDF be called?

WebWhen we plot a continuous distribution, we are actually plotting the density. The probability for the continuous distribution is defined as the integral of the density function over some range (adding up the area below the curve) The integral at a point is zero, but the density is non-zero.
